WATER GIRCU'LATOR FOR AUTO ENGINES.

, Application filed. June 27, 1921. Serial No. 480,666.

To all whomm't may concern:

Be it known that we, Go'rTLInB ,MULLER and MATHEW B. HILL, citizens of the United States, residin in the city and county of Philadelphia, btate of Pennsylvania, have invented a new and useful lVater Circulator for Auto Engines, of which the following is a specification.

Our invention consistsof a novel construction of a mechanical water impelling device and its adjuncts and novel means for actuating the same, which are adapted to be installed'in the water circulating or cooling system of an internal combustion engine of the character commonlyemployed in automobiles and the like, wherein a radiator, a cooling fan and connections from the water jacket of the engine to the top and bottom of said radiator are employed, provisionbeing made for automatically operating the mechanical impeller or water circulator from the engine shaft pulley which drives said fan by its frictional contact with a contiguous pulley, which by means of a belt drives the pulley, actuating the water circulating device.

It further consists of novel means for effectually maintaining frictional contact between the engine shaft pulley and the pulley which drives the mechanical impeller or water circulator.

It further consists of novel means for rendering our device applicable to the cooling system of an automobile engine of standard construction, without necessitating the dismantling or reorganizing of any of the standard fan operating mechanisms now employed.

It further consists of other novel features of construction and advantage, all as will be hereinafter fully set forth.

For the purpose of illustrating our invention, we have shown in the accompanying drawings a form thereof whichis at present preferred by us, since it will give in practice satisfactory and reliable results although it is tobe understood that the various instrumentalities of which our invention consistscan be variously arranged and organized and that our invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described. 7 1

Figure 1 represents a side elevation of a water circulator and its adjuncts for automobile and other engines'embodying our invention. r I 1 Figure 2 represents on an enlarged-scale, a sect on on line 2-2 of Figure 3. i

Figure 3 represents a section on line 33 of Figure 2.

Figure 4: represents-an end view of Figure 1 with the radiator and fan removed.

Figure 5 represents on an enlarged scale a side elevation of certain of the mechanism seen inF-igure 4;.

Figure 6 represents a top plan view of Figure 5.

Figure 7 represents a perspective view showing the manner of making the frictional contact between the engine shaft pulley and the pulley which drives the water circulator. Similar numerals of reference indicate corresponding parts.

Referring to the drawings 1 deslgnates the cylinder or cylinders of an internal combustion or automobile engine,

the same being provided with water jackets of the conventional type, from the upper portion of which leads the connection 2 to the top of the radiator 3, while from the bottom of said radiator'leadsthe connection 4, which communicates with the housing 5, which is connected to the outlet pipe 6, which leads to the water jacket surrounding the engine cylinders.

7 designates a pulley mounted on the engineshaft 8 around whichpasses the belt 9, which drives the pulley 10, which actuates theifan 11. The engine shaft pulley 7 has in friction contact therewith the elongated roller 12*, which revolves in unison with the pulley 12. ,Boththe roller 12 and the pulley 12 rotate in unison and are mountedon the shaft 13, which has its bearings in the end of the arm 14, which is pivotally mounted at its opposite end 15 upon the lug 16. The arm 17-is fixed, its left-hand end as seen in Figures 4 to 6 being secured to a suitable to engage or to be secured to the under side of the bearing for the shaft '13, as will be understood from Figure 5, whereby there is a constant but yielding downward pressure exerted at all times on the friction roller 12 so as to cause the same at all times to frictionally engage with the periphery of the engine shaft pulley 7, so as to rotate in unison therewith. 23 designates a belt passing around the pulley 12 and thence to the pulley 24 mounted on the impeller shaft 25, which is suitably packed, as indicated at 26 and has an elongated bearing 27 within the housing 5, the inner end of said shaft 25 being provided with the impelling device or water circulator 28, comprising the band or rim 30, and the spiral blades 31 which are located in the housing 5.

Between the side terminals of the blades are the passages 29, through which the cooling medium is adapted to flow on its way from the outlet end of the housing to the pipe or conduit 6.

It will'be seen from the foregoing that as the engine shaft 8 rotates, the engine shaft pulley 7 will also rotate and by reason of the belt 9 will rotate the pulley 10 and the fan 11, as is customary.

As the engine pulley 7 rotates, it will be apparent that by the frictional contact of the roller 12 therewith, said roller and the pulley 12 will be rotated and through the medium of the belt 23 the small pulley 2a will be rotated, thereby rotating the impeller wheel shaft 25 and the impeller wheel or water circulator 28, whereby a positive upward circulation of the cooling medium will be imparted from the pipe 4: through the housing 5 to the pipe 6, thence into the jackets of the engine cylinders and thence through the pipe 2 into the radiator 3.

It will thus be seen from the foregoing that we provide a forced circulation of the cooling medium through the medium of the impeller wheel or circulator 28, so that the necessary power or energy to lift the cooling medium from the bottom of the radiator 3 upwardly into the engine jackets and thence into the top of the radiator is effectively provided, it further being apparent that the lifting power of our device is located or concentrated at such a point that the cooling medium will be forced into the engine jackets and thenceinto the upper portion of the radiator regardless of slight variations in the water level or temperature of the cooling medium which might otherwise .cause the circulation thereof to stop.

pulley, so that the latter will by its fric tional contact wit-h the roller 12 drive the same, whereupon the rotation of the me chanical propelling device or circulator 28 is effected. The roller 12 and the pulley 12 revolve as a unit, and the roller 12* is at all times pressed into contact with the pulley 7 by the spring 21.

It will further be seen that our device when once installed is entirely automatic in its operation and requires no attention on the part of the driver or chauffeur of an automobile, since on the starting of the engine,the engine shaft pulley 7 will be rotated and its rotation will be imparted to the mechanical impeller or circulator 28, through the medium of the intermediate connections.

It will be apparent that any suitable form of impeller or water circulator may be emp'loyed, which by its rotation will impel the cooling medium in the direction desired.

It will now be apparent that we have devised a new and useful water circulator for auto engines which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while we have, in the pres ent instance, shown and described a preferred embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that such embodiment is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages. 7

Attention is drawn to the fact that the circulator 28 in the present instance is coInposed of the peripheral cylindricalband 0r rim 32 and the blades 31 as aforesaid, the former surrounding the latter and having its outer face running freely upon'the inner face of the housing 5 in which SLl(l'ClIOU. latoris mounted.

The band 30 serves as a flange around the blades to prevent the water that passes out between the blades from spreading against said inner face of'the housing at thepart around said band and so it is-not restrained and checked in its passage through exit-0f the circulator while on-the contrary the-*Water is directed from the blades in a solid 116 body from the same'into the pipe 6, and so is rendered more effective in its entrance into the latter andsubsequent places.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is I a 1.
